Abstract

The core of the work roll consists of an iron alloy, and the shell of the roll consists of an iron alloy having the following constituents in % by weight: C = 2 - 3.5, Cr = 10 - 25, Mo less than 5, Ni less than 2, Mn less than 2 and Si less than 1. These known work rolls have the disadvantage that they cannot be used universally in spite of a comparatively high wear resistance, for example not in the first stands of a finishing step for special sheet grades and of hot-rolled strip lines. To eliminate these disadvantages, the Ni content of the iron alloy of the shell is increased to 4 - 6 % by weight. In other respects, the usual composition of high-chromium rolls is maintained. As a result of this effect on the metal structure matrix, the disadvantageous properties of the known work rolls are eliminated, with unchanged carbide structure. Surface hardnesses between 60 and 100 ShC can be achieved.
